The rotating sub-controlling system 201 is connected to the electrical control device 10 so as to receive rotating control commands and send control signals on the basis of the control commands, thereby making the wok 11 perform various rotation motions and controlling the rotation direction and speed of the wok 11. The stir-frying function of the present embodiment realizes various stir frying effects in the way of rotation motions combination control, which is similar to a roller rotating and stirring. Various effects like saute-stirring and stir-frying can be realized by combining various rotation modes including high-speed rotation, low-speed rotation, clockwise rotation and anti-clockwise rotation. By cooperatively using stirring pieces arranged in the wok 11 and controlling the rotating angle of the wok 11, the stir frying effect like tossing the pan can be realized.

Referring to FIG. 6, the electromagnetic heating controlling device 5 comprises an electromagnetic sub-controlling system 501, a wok temperature detector 502 and a high frequency driving source 503, the wok temperature detector 502 is used for detecting the temperature of the wok body and sending the detected data to the electromagnetic sub-controlling system 501. The high frequency driving source 503 is connected to the electromagnetic heating coils 12 so as to generate current for the electromagnetic heating coils 12. The electromagnetic sub-controlling system 501 is connected to the electrical control device 11 so as to receive turn-on, turn-off and heating control commands, control it to open, close, turn-on or turn down the high frequency driving source 503 on the basis of the detected data of the wok temperature detector 502, so that heating time and current intensity of the electromagnetic heating coils 12 can be controlled and thus heating time and heating temperature for the wok 11 can be controlled. In the present embodiment, the function of precise heating control required by Chinese culinary art is realized by controlling heating temperature and heating time. The heating temperature is controlled by adjusting the current intensity of the electromagnetic heating coils 12 and making the wok temperature stable in the range of controlling value. Since the electromagnetic heating does not have time-lag, heating control performed in this way is much more sensitive than that performed in other ways such as traditional open fires and resistance generating and conducting. When further cooperatively employing precise control of heating time, the function of heating control required by Chinese culinary art can be fully realized. It can be understood that, the electromagnetic heating controlling device 5 of the present embodiment may be fixedly mounted on the wok frame 305.

In the present embodiment, the ingredients are stocked in a four-compartment standard package box 61 (referring to FIG. 8) and particularly are stocked respectively in individual compartments (compartment A, compartment B, compartment C, compartment D) of one package, wherein various major ingredients and accessory ingredients are selected for various dishes. Furthermore, an electronic tag 611 (two-dimension codes, IC card, RFID, etc.) is attached to the bottom of each standard package box 61. The recommended recipe programs of the standard package, or various information, such as production, storage, delivery, selling information of major ingredients and so on, may be obtained by reading and writing (for example reading by means of the multimedia man-machine interface 11) the information of the electronic tag for common automatic cooking machines to use. According to the control program of the automatic cooking machine, the automatic ingredient feeding device 6 provides major ingredients and accessory ingredients stocked in respective compartments at a predetermined time in a predetermined sequence, wherein the combinations of feeding sequence for each Chinese dish may have up to 24 changes.

The Chinese dish recipe of major ingredients and accessory ingredients, which is a part of Chinese culinary art, usually consists of one to three major ingredients and several accessory ingredients. For example, the dish “fried sliced cabbage” uses cabbage as a major ingredient, and uses chili, garlic and so on as accessory ingredients. The dish “Sliced Meat with Dry Tofu and Green Pepper” uses shredded green pepper, shredded meat, and dry tofu as the major ingredients, and uses garlic and red pepper as accessory ingredients. The major ingredients and accessory ingredients of a Chinese dish are respectively placed in respective compartments of one package, depending on whether these major ingredients and accessory ingredients can be put into the wok at the same time. The major ingredients and accessory ingredients which can be put into the wok at the same time may be stocked in one compartment. If the major ingredients and accessory ingredients of a certain Chinese dish are placed in a package with four standard compartments, it means the major ingredients and accessory ingredients can be put into the wok in four groups at four different stages at most, thus it has 24 feeding sequence combinations at most (abcd, abdc, acbd, acdb, adbc, adcb, bacd, badc, bdac, bdca, bcad, bcda, cabd, cadb, cbad, cbda, cdab, cdba, dabc, dacb, dbac, dbca, dcab, dcba). Generally, it is enough to meet the requirement of Chinese culinary art for most dishes. Moreover, a standard package with more compartments, such as six compartments or eight compartments, may meet the requirement of more complicated cooking technique and meet the feeding requirement of high grade commercial automated cooking machines.

The key point for realizing industrialization of the automated Chinese dish cooking machines is that, the major ingredients and accessory ingredients of a certain Chinese dish are selected according to various cooking requirements, stocked in a standard package and particularly stocked respectively in individual compartments of one package. Thus, a complete industrial chain, including the specialized production of agricultural products in the upstream, pre-treating (cleaning and cutting etc.) on the spot, packaging at the consumption place, delivery, and consumption of the automated cooking machine, can thus be established. It brings a new life style, which is different from the traditional style buying primary agricultural products in markets and producing large quantity of living rubbish. On the other hand, due to the use of standard package, the production of the agricultural products may realize intensification, large-scale, standardized and industrialization production, which provides a back tracking mechanism for food safety guarantee. In addition, Internet of Things technology, such as two-dimension codes, IC card, RFID and so on, may be applied to the standard package of major ingredients and accessory ingredients and preset in the package, so as to facilitate the identification of recommended recipe program and other agricultural products information for general automated cooking machines.
